Remember when you were a child first learning to tell time? Yes, it was challenging, but that made it all the more thrilling when you finally figured it out! Well, here's a clock that'll bring that challenge back again. The Pop Quiz Clock doesn't have your typical numbers 1 through 12. In their place, it has mathematical equations, formulae, and expressions that represent those numbers. For instance, ten o'clock is expressed as -8 = 2 - x. Seven o'clock is displayed as 52 - x 2 + x = 10. Many of the expressions require symbols we can't display on this web page, so take a look at the photo to see how it's done. The clock measures 11-1/2" and has white numbers on a textured, blackboard-type surface. So if you've mastered digits and Roman numerals, get yourself a Pop Quiz Clock and make telling time difficult again!

Charles Darwin Little Thinker Just like human beings and finches, dolls evolve, too. Compare a 1920s Raggedy Ann to a 1960s Barbie Doll, and you'll see just what we're talking about. So it seemed only fitting that a doll should evolve into the Master of Evolution himself. Our Charles Darwin Little Thinker Doll is as adorable as Darwin was brilliant. He stands about 12 inches tall, looking every bit the scholar in his gray suit. He also has a full beard, bushy eyebrows, and a bald head as befits a genius of his stature. He's cute, cuddly, and even a bit inspiring. So get yourself a Charles Darwin Little Thinker Doll -- It would be a natural selection! |
